摘要:
An energy-efficient method for producing purified, compressed carbon dioxide (435) suitable for enhanced oil or gas recovery (EOR/EGR) and electricity from a gaseous hydrocarbon feed (100) using a SOFC system (1), the method comprising inter alia the steps of: introducing the gaseous hydrocarbon feed (100) into the SOFC system (1); adding a recycled anode off gas comprising hot steam (309) to the hydrocarbon feed (100); introducing the hydrocarbon feed ( 100) comprising hot steam into a reformer ( 108) of the SOFC system (1); generating a reformed process gas (109) in the reformer (108); passing the reformed process gas (109)into the solid oxide fuel cell (2); in the solid oxide fuel cell (2), converting hydrogen and carbon monoxide of the reformed process gas (109) into an anode off-gas (301) and into a depleted air (208); separating the anode off-gas (301) into a recycled anode off-gas (304) and a remaining off-gas (320); recycling the recycled anode off-gas (304) above condensation temperature to provide the recycled anode off gas comprising hot steam (309); passing the remaining anode off-gas (320) into a water- gas shift unit (322); in the water-gas shift unit (322) create a shifted anode off-gas (326) and passing the shifted anode off-gas (326) into a separation system (400) to create compressed carbon dioxide (435).

Said first (2) and second layers (3) are disposed with a with a gas distribution structure (11) forming a pattern for a reactant fluid flow. An inlet opening is provided for the supply of reactant fluid to the gas distribution structure (11) formed between the first layer and the second layer by said pattern and an outlet opening is provided for discharging reaction products from the gas distribution structure (11). A supporting layer (4) is provided for tempering the first layer (2) for regulating the temperature of the reactant fluid or of the first layer.
摘要:
The present invention includes systems, devices and methods for mechanically interfacing between a pump and an infusion kit or conduit, and methods and materials for producing same. According to some embodiments of the present invention, there may be provided a mechanical pump-tube interface unit adapted to detachably connect to a pump. The mechanical pump-tube interface unit may be adapted to hold a fluid conduit/tube positioned such that when the interface is attached to a pump the pumping mechanism of the pump acts upon the fluid in the tube. A mechanical pump-tube interface unit may include physical adaptations designed to prevent longitudal and/or rotational movement, in relation to the unit, of a fluid conduit/tube held by or attached to the interface unit. According to further embodiments, a segment of conduit/tube may be attached/connected to a mechanical tube-interface during the assembly of the interface unit, to form one integral unit including the conduit/tube segment secured/trapped within.

The linear bearing (3) comprises a plurality of concentrically arranged springs (2), each spring (2) being designed as a plate spring with a fixing part (2a) and a bore (2c) arranged in the center (Z). Each spring (2) also has a spring arm (2b) which emerges from the fixing part (2a) and ends in an end section (2g). The end section (2g) has the bore (2c), and the bore (2c) is concentric to the fixing part (2a). Each spring (2) has a direction of movement (B) which runs perpendicular to the fixing part (2a), and the springs (2) are arranged one behind the other in the direction of movement (B). The spring arm (2b) has a spring arm section (2ba) which runs concentrically with the bore (2c) and which extends along an angular range (γ) between 100° and 270°, preferably along an angular range (γ) between 180° and 300°. The fixing part (2a) is at least partly annular, and the spring arm section (2ba) has, in a radial direction with respect to the bore (2c), a width (2k) which is at least five times greater than the thickness (2i) of the spring arm (2b). The width (2k) of the spring arm section (2ba) is designed such that the spring arm section extends relative to the annular fixing part (2a) and the end portion (2g) while forming a lateral gap (2d).

摘要:
Configurations and methods of reducing oxygen infiltration into an oxygen-sensitive process environment of a plant are presented in which carbon dioxide is isolated from a process stream within the plant, and in which a small portion of the isolated carbon dioxide is used in the plant as a transport gas or a seal gas for devices that are known to exhibit air in-leaking.
摘要:
Post-combustion conditioning systems are described that include a flue gas conditioning device configured to condition an exhaust stream to produce a conditioned stream. First and second outlet ducts can be fluidly coupled to, and substantially supported by, the flue gas conditioning device. This advantageously can eliminate costly ductwork, reduce the space required, and reduce the pressure drop of the system. The first outlet duct can fluidly couple the flue gas conditioning device to an exhaust duct, such that the conditioned stream can flow from the first conditioning device via the first outlet duct.
